Bitcoin, whose price has soared roughly 1,500% since the start of the year, got a lift from the new activity on the Chicago exchange.

It jumped about 8% in less than 10 minutes -- to more than $15,700 -- after the futures trading began, according to data from CoinDesk, which values bitcoin based on data from four exchanges.

By late Sunday, it was trading above $16,000. And on the futures exchange, contracts expiring next month were trading above $17,000.

Some leading economists and financiers are calling bitcoin a bubble and a fraud, but industry insiders say they think it's only going to get bigger as it gains more widespread acceptance.

Currently, bitcoins are bought and sold on unregulated virtual exchanges -- and it's been extremely volatile.

Last week, in the run-up to its futures trading debut, bitcoin's value soared on some exchanges from less than $10,000 to $17,000 before dropping back to near the $15,000 mark, spurring renewed warnings of a bubble.

Stephen Bielecki, an attorney with Kleinberg Kaplan, told CNNMoney this weekend that offering bitcoin futures may help "rationalize" the price.

Futures are contracts that let investors buy or sell something at a specific price in the future.

Offering futures contracts for bitcoin allows investors to speculate on the digital currency's price without actually owning any bitcoin. That's good news for mainstream investors who want to place their bets on bitcoin, but may be nervous about purchasing the actual currency.

The option also gives investors an easy way to bet against bitcoin, which could snap its streak of nearly unfettered gains.

There's been a few sharp dips, but bitcoin's rise has been stunning. In 2011, it once traded for about $3, according to CoinDesk.
